Hinkley Valve Adjustment

onMay 17, 2012

Follow the manual to remove the valve covers etc and measure valve clearances. This is where my brain starts to hurt as my feeler guauges are imperial, and I think in Thou, and I have trouble keeping track of what shim I need and where it goes. Try this spreadsheet Valve Shim enter clearance in thou, existing shims in mm (if you can’t read the shim use a vernier Caliper to measure thickness) then the required shims are calculated.

Measure clearances and enter in green cells or if in mm enter in blue cells.
